Welding method for latticed column and pipe pile

Abstract

The invention relates to the technical field of welding, and discloses a latticed column and tubular pile welding method which comprises the following steps: judging whether welding conditions are met or not according to an environmental particle concentration value, and determining initial welding power according to a welding contact length; acquiring a temperature index value corresponding to each temperature analysis point, comparing the environment temperature value with historical data, determining a temperature similarity according to the environment temperature value and the historical data, determining a power adjustment coefficient according to the historical data when the temperature similarity is greater than or equal to a similarity threshold value, and determining a power adjustment coefficient according to the historical data when the temperature similarity is less than the similarity threshold value. Generating temperature response marks for the corresponding temperature analysis points according to the temperature index values, extracting feature points from the processed multidirectional images, combining the processed multidirectional images to obtain a welding image, judging whether repair welding is carried out or not according to the welding image, and adjusting target welding power according to the welding length and the welding contact length. The method has the characteristics of good dynamic adjustment and accurate welding.
